Which then leaves the dillema that you then can't reseed the perennial
bluegrass, in the fall. The pre-emergent doesn't care who's seed is trying
to poke through the barrier.
Poa annua sucks. I can't imagine trying to rid it from a lawn of P.
pratensis. They're the same genus. Even /if/ such a selective herbicide
were available, being species-specific would put it well out of reach of a
homeowner, both in cost as well as by government regulations.
